NASA crashed a spacecraft into an asteroid in 2022; Europe's Hera probe reaches impact site to investigate if Earth can be saved from space rocks

Europe’s Hera spacecraft has reached the asteroid system where NASA’s DART mission deliberately struck Dimorphos in 2022. Hera will examine the impact site and measure the collision’s effects, including the asteroid’s structure and the crater left behind. The mission is intended to improve understanding of whether a spacecraft could alter an asteroid’s path and help protect Earth from a future space-rock threat.
